This study investigated the changes in the nutraceutical lipid components of brown rice oil after germination. Four different high-yielding cultivars (Dasan1, Segyejinmi, Hanareum1 and Hanareum2) of Korean brown rice were selected and brown rice oil was extracted from each cultivar before and after germination. Free fatty acid, squalene, policosanols, and isomers of phytosterol were analyzed using GC, and isomers of tocols (tocopherol and tocotrienol) and γ-oryzanol were quantified using HPLC from both brown rice oil (BRO) and germinated brown rice oil (GBRO). The contents of phytosterol isomers, campesterol, stigmasterol, and β-sitosterol were increased by 8.3%, 31.6%, 3.3% in GBRO, respectively. Furthermore, the squalene content showed the highest increase of up to 2.4 fold in GBRO compared to BRO. In addition, linoleic and linolenic acid composition increased whereas oleic and palmitic acid decreased in the GRBO. However, the contents of tocols (tocopherol and tocotrienol) in GBRO were lower than those in BRO, and there was no significant difference in policosanol and γ-oryzanol between GBRO and BRO. These results suggest that GBRO has the potential as a healthy and functional source due to its lipid profile on improved lipid metabolism.

This study was conducted to examine the effects of Opuntia ficus-indica complex (OF) on the lipid metabolism, bile acid in feces, alanine aminotransferase (ALT) activity, aspatate aminotransferase (AST) activity, composition of urine and expression of cholesterol related mRNA in streptozotocin (STZ)-induced diabetic rats. Thirty two male Sprague-Dawley rats were randomly divided into non-diabetic control (NC), diabetic control (DC), diabetic OF of 2% (OF-2) and diabetic OF of 5% (OF-5), then each group was fed for 3 weeks. Plasma total cholesterol, non-esterified fatty acids (NEFA), total cholesterol, low density lipoprotein (LDL), very low density lipoprotein (VLDL) were decreased significantly (p<0.05) in OF-5 group compared to DC, but high density lipoprotein (HDL) was not changed. AST and ALT were also reduced and bile acid excretion was improved. Composition of urine in OF-5 was almost same in NC. The expression of cholesterol 7α-hydroxylase (CYP7A1), 3-hydroxy-3-methylglutaryl-coenzyme A reductase (HMG-CoA-R), Low density lipoprotein receptor (LDL-R) mRNA indicated that feeding OF have the effects of cholesterol decreation in plasma by synthesis of bile acid from cholesterol. These results provide experimental evidence about improved lipid metabolism of the OF feeding in the STZ-induced diabetic rats.

This study was carried out to investigate the effects of feeding the broilers that are exposed to extreme heat stress by control of inverse lighting times with night restricted feeding of extreme heat diet(EHD1, 2: extreme heat diet) containing different amount of soy oil, molasses, amino acids and vitamin C on short chain fatty acid and blood lipid profile. 300 broiler chickens(Abaica strain) were randomized into four dietary treatment groups according to a randomized block design on the day they were hatched. The four dietary treatment groups were: T1(EHD 1, 10:00~19:00 Dark, 19:00〜10:00 Light), T2(EHD 2, 10:00〜19:00 Dark, 19:00〜 10:00 Light), T3(EHD 1, 09:00〜18:00 Dark, 18:00〜09:00 Light), T4(EHD 2, 09:00〜18:00 Dark, 18:00~09:00 Light). The body weight gain of the broilers was highest in T2, and high in order T1, T4, T3(p<0.05). Weights of the lymphoid organ, thymus and bursa of Fabricius were high in T1, T2 as compared to T3, T4 but spleen was lower in T4 than T1, T2, T3(p<0.05). Blood triglyceride, total cholesterol and glucose were higher in T1, T2 than T3, T4(p<0.05). LDL-C was high in orderT4, T3, T2, T1 but HDL-C showed the opposite trend(p<0.05). Blood concentrations of IgG, IgG and IgM were higher in T1, T2 than inT3, T4, but the corticosterone concentration decreased significantly in them. In T1 and T2, Lactobacillus in the feces increased, but total aerobic bacteria, E.coli, coliform bacteria was decreased rather significantly, compared with those in T3 and T4(p<0.05). Concentrations of acetic acid, propionic acid and total SCFA in cecum were high in order T2, T1, T3, T4, but butyric acid, isobutyric acid, valeric acid, isovaleric acid were lower in T1, T2 than in T3, T4 (p<0.05).

This study investigated the effect of Dolichos lablab extract on the lipid metabolism of rats fed a high fat and cholesterol diet. S-D male rats (n=48) were given 40, 400, or 4000 mg/kg of Dolichos lablab extract and fed a high fat and high cholesterol diet for four weeks (DL-HFC group). As a result, serum levels of total lipids, total cholesterol, and triglycerides were higher in the high fat and high cholesterol group (HFC-group) than the control, and significant differences were observed between the control and the DL-HFC (40, 400, 4000 mg/kg) group. The fat absorption rate increased with a high fat diet feeding, but was higher in the DL-HFC (40, 400, 4000 mg/kg) group.

To investigate the effects of coated liposome from Discorea rhizoma extract (DRE) in streptozotocin (STZ)-induced, we evaluated changes in body weight, fasting blood glucose, blood insulin and blood lipid concentrations in mice. Mice were divided into four groups: (DC), diabetic DRE at 10 ㎎/㎏ (DRE-1), diabetic DRE at 50 ㎎/㎏ (DRE-2), and diabetic DRE at 250 ㎎/㎏ (DRE-3). Mice had free access to water and diet (10 weeks). The DC group showed higher blood cholesterol than the DRE-1, DRE-2, DRE-3 groups. In glucose tolerance test, the DRE-1, DRE-2, and DRE-3 groups increased after 30 minutes in decremental glycemic response area under the curve. Fasting blood glucose levels in the DRE groups significantly decreased through 4 weeks. Plasma total cholesterol, triglyceride and LDL-cholesterol concentrations were also lower in the DRE groups. On the other hand, the DRE-1, DRE-2 and DRE-3 groups showed higher HDL-cholesterol and insulin levels than the DC group. Moreover, blood glucose and lipid levels significantly decreased in streptozotocin (STZ)-induced diabetic mice treated with DRE. These results indicate that DRE may reduce elevated blood glucose levels and serum lipid concentrations in hypoglycemic and diabetic mice, suggesting its usefulness as a functional food.

Our objectives in this experiment were to study the effects of oils that are high in contents of unsaturated fatty acids (olive, flaxseed, and perilla oils) and pyroligneous liquor on plasma lipid concentrations in mice. Male ICR-mouse (n=10 per group) were fed powdered form diets containing oil and pyroligneous liquor for 60 days. The cholesterol level of the PP group (96.71±25.75 ㎎/㎗) was lower than that of the COW group (133.56±21.53 ㎎/㎗). Levels of triglyceride of COP, CFP, and CPP groups were 121.10±50.79 ㎎/㎗, 77.80±38.58 ㎎/㎗, and 92.40±33.04 ㎎/㎗, respectively (p<0.05). The dietary addition of olive oil increased the plasma lsevels of cholesterol and LDL-cholesterol. On the other hand, the dietary addition of flaxseed oil and pyroligneous liquor increased the plasma level of HDL-cholesterol and decreased the plasma levels of LDL-cholesterol and triglyceride compared with those of the control group. Further, the dietary addition of perilla oil decreased plasma triglyceride but increased HDL-cholesterol. The decrease in the cholesterol level was much higher in the CFP group. In conclusion, the dietary addition of long-term pyroligneous liquor effectively decreased the plasma levels of cholesterol and triglyceride and increased the plasma level of HDL-cholesterol. The additional dietary administration of flaxseed and perilla oils increased the effect of pyroligneous liquor.

본 연구는 연속조명과 함께 폭염 스트레스(extreme heat stress, EHS)에 노출된 브로일러에서 폭염사료 급여가 혈액지질, 성장능력, 면역기관, 혈청 면역물질, 맹장 미생물 변화에 미치는 영향을 조사하였다. 일반 환경온도 (25℃) 또는 폭염스트레스 (33±2℃)하에서 사육한 병아리는 일반사료(chow diet, CD)와 폭염사료(extreme heat diet, EHD)를 섭취하였다. 부화 당일 Ross 308 병아리 500 마리를 5 처리구 4 반복(반복 펜 당 25 마리)으로 완전임의배치 하였다. T1 (일반환경+CD), T2 (EHS+CD), T3 (EHS+CD 내 우지를 대두유로 대체 및 당밀 5%를 함유하는 EHD), T4 (EHS+CD 내 우지를 대두유로 대체, 당밀 5%, 메치오닌과 라이신을 각각 CD 의 1.5 배씩 함유하는 EHD), T5 (폭염+CD 내 우지를 대두유로 대체, 당밀 5%, 메치오닌과 라이신을 각각 CD 의 1.5 배씩 추가 및 비타민 C 300 ppm 을 함유하는 EHD)로 구분하였다.

This study was performed to investigate the effects of ethanolic extract of Ulmus davidiana root (UE) on lipid metabolism in mice fed a high-fat diet (HF) for 7 weeks. Forty male ICR mice were randomly divided into four groups; normal diet group (N), high-fat diet group (HF), HF with 0.5% UE (HF-L) and 1% UE (HF-H) group. Body weight, body weight gain, and liver weight in the HF group was significantly higher than in the N group, while those of the HF-L and HF-H group were unchanged. UE improved HF-induced dyslipidemia by reducing serum triglyceride, total cholesterol, and the atherogenic index. There was no difference in serum HDL-cholesterol among experimental groups. However, the HDL-cholesterol/total cholesterol ratio was significantly increased in the HF-L and HF-H group. Histological analysis showed that HF-fed mice developed hepatocellular microvesicular vacuolation as a result of fat accumulation. These changes were attenuated by 1% UE supplementation. In addition, hepatic triglyceride and cholesterol levels in the HF-H group significantly reduced. Taken together, these results demonstrated that lipid levels in the blood and liver were reduced by UE, suggesting that it might be beneficial for the prevention and treatment of hyperlipidemia and fatty liver.

This study investigated the effects of the diet with Cucurbita moschata (CM), adlay seed (AS), and Cudrania tricuspidata leaf (CTL) mixed-powder on the visceral fat, fecal amount, and serum lipid profiles in rats fed a high-fat diet (HFD). The mixed ratio of CM, AS, and CTL as a functional food ingredient was 1:1:1 on a weight basis. Male Sprague-Dawley rats were fed a high-fat diet (D12492; 45 kcal fat) for 5 weeks during the first phase. In the second phase, which lasted 5 weeks, the rats were divided into six experimental groups. The groups were: a high-fat diet group as a control during the 10 weeks of experimental period; and a high-fat diet with 5, 10, 15, 20, and 30% mixed powder supplement group. The adipose tissue (RFP, EFP) weights were significantly decreased in the 20% and 30% mixed powder supplement groups than in the HFD group (p<0.05). The fecal weight produced by the 15%, 20%, and 30% mixed powder supplement groups was significantly increased during the second phase compared to the first phase (p<0.05). In terms of serum lipids, TG (triglyceride) content was decreased in the 10% and 15% mixed-powder supplement groups. The blood glucose levels were significantly decreased in all experimental diet supplement groups than in the HFD group (p<0.05). The findings show that the high supplement groups could improve the visceral fat accumulation, fecal amount, and blood glucose content compared to the HFD group.

In this study, the effects of intake of Acer mono Max. seed oil, and Magnolia denudata seed oil on the lipid levels of mouse blood were compared to those of commercially available vegetable oils. FiveICR mice were each fed a corn oil, Acer mono Max. seed oil, and Magnolia denudata seed oil supplemented diet for a total of 8 weeks. The serum profiles of mice fed Acer mono Max. seed oil and Magnolia denudata seed oil were high in palmitic acid, oleic acid, and linoleic acid. The saturated fatty acid contents of mice fed Acer mono Max. seed oil and Magnolia denudata seed oil were 3.95% and 0.88%, whereas the unsaturated fatty acid contents were 8.71% and 4.60%, respectively. The liver and spleen weights of mice fed Acer mono Max. seed oil were higher than those fed corn oil (p<0.05). Total cholesterol level was highest in mice fed Acer mono Max. seed oil (p<0.05), whereas there were no significant changes in the cholesterol levels of mice fed Magnolia denudata seed oil and corn oil. The HDL-cholesterol levels in mice fed Acer mono Max. seed oil (175.80±27.66 ㎎/㎗) and in those fed Magnolia denudata seed oil (145.20±19.10 ㎎/㎗) were higher compared to those of mice fed corn oil (p<0.05). In conclusion, there were no significant differences in fatty acid composition between mice fed Acer mono Max. seed oil and Magnolia denudata seed oil. Future study on the antioxidant effects of seed oils should be carried out.

This study was conducted to investigate the effects of brown rice and brown rice phytosterol on blood pressure and lipid levels in spontaneously hypertension rats (SHR). SHR were grouped according to blood pressure and fed either a control diet or experimental diets containing 50% brown rice powder or 5% brown rice phytosterol for 3 weeks. Body weight gain and epididymal fat weight were significantly reduced in the brown rice powder and brown rice phytosterol groups compared to control. Brown rice and brown rice phytosterol diets suppressed age-dependent increases in systolic blood pressure compared to control. In addition, brown rice and brown rice phytosterol diets decreased total lipid, triglyceride, and cholesterol levels in the liver, whereas serum HDL cholesterol increased. Lastly, brown rice phytosterol reduced TBARS contents in the kidney. These results suggest that brown rice and brown rice phytosterol exert antihypertensive effects that improve lipid metabolism in SHR.

Negative implications of indiscriminate use ofherbicides in agricultural systems have forced the scientific community to develop alternate weed control strategies. Allelopathy appears one of the possible alternatives for achieving sustainable weed management. Study was designed to evaluate the allelopathic potential of sunflower (Helianthus annuus L. cv. Azargol) water extracts on germination, early seedling growth and lipid peroxidation of Johnson grass (Sorghum halepnse) and wild mustard (Sinapis arvensis). Three levels of sunflower water extract viz. 5%, 10% and 15% were evaluated against both species in two separate experiments by using distilled water as control. Sunflower water extracts considerably delayed and reduced the germination percentage, along with fresh weight and length of both Johnson grass and wild mustard seedlings. Highest reduction was noticed at higher concentration (15%) of sunflower water extract. Nonetheless, sunflower water extract application enhanced malondialdehyde content (lipid peroxidation) along with reduced activities of antioxidants (catalases and peroxidases) in both Johnson grass and wild mustard seedlings. Such effects can be explored further under field conditions

본 연구는 포장방법과 저장기간에 따른 국산대두와 연해주 대두의 이화학적인 특성을 조사하기 위하여 TBA test, 산가, POV, fluorescence spectrum test를 실시하였다. 저장 기간이 경과함에 따라 TBA test는 국산대두와 연해주 대두 모두 실험기간 내 포장방법에 따른 유의적인 차이는 있었으나 전체적인 경향은 차이가 없었다. 산가는 국산 대두에서 16일차에 유의미한 차이를 보였으나 20일차에서는 모두 유의차를 보이지 않는 것을 알 수 있었다. 연해주 대두의 경우 저장기간 동안 포장방법에 따른 차이가 없었다. POV의 경우 국산대두에서 저장 16일차까지 유의한 차이가 없었으나 진공포장 20일차에서 1.85 meq/kg oil로 값이 증가하였다. 연해주 대두에서는 초기값과 저장 20일차의 측정값이 10%내의 변화를 보이고 함기포장과 진공포장, 질소충진포장과의 유의차를 나타내지 않아 포장법에 의한 산패도의 차이를 찾아내지 못하였다. Fluorescence spectrum test를 이용한 측정에서는 국산 대두의 경우 같은 경향을 나타내었다. 연해주 대두의 경우도 저장방법 별 산패도 값의 차이는 존재하였지만 같은 경향을 나타내는 것을 알 수 있었다. 연구결과를 토대로 fluorescence spectrum test를 이용하여 산패도를 측정하는데 적합하다고 판단된다. 또한 요오드가, 검화가, 비중 측정을 통해 포장방법과 저장기간을 통한 변화를 측정하였으나 유의할 만한 차이를 나태내지 못하였다. 결과적으로 국산대두와 연해주대두의 저장기간 20일 동안의 산패도의 증가는 나타나지 않았고 포장방법에 따른 산패도의 차이는 없었다. 본 연구의 결과는 연해주산 대두를 수입할 경우 유통기한 중 질소충진과 같은 고비용의 포장법을 적용하지 않더라도 수입 시에 품질변화가 거의 이루어 지지 않음을 보여 주어 실질적으로 국내 소비자에게 연해주산 non-GMO 대두를 경제적으로 공급이 가능함을 보여주었다. 또한 20일의 저장기간 동안 변화가 매우 적음은 현재 대두의 분말가공에 시도되고 있는 집결지 최소가공방식의 최소가공량을 2-3배 확장하여 집결지에서 보다 많은 양을 가공 저장하여 수송함이 가능함을 보여 주고 있다. 이는 연해주대두의 경제적 활용가능성을 보다 높여 줄 것이라 판단된다.

본 연구는 산란계 사료 내 돼지감자(Helianthus tuberosus L.)로부터 제조한 미세캡술화 이눌린(microcapsulated inulin, MI)의 고수준 첨가가 혈액지질, 계란콜레스테롤 및 지방산조성에 미치는 영향을 조사하기 위해 실시하였다. 25주령 갈색산란계를 이용하여 4주 동안 실험사료를 급여하였으며, 실험처리구는 MI 무첨가 대조군, 800 ppm, 900 ppm 및 1,000 ppm로 구분하였다. 혈액 중성지방, 총콜레스테롤 및 계란 콜레스테롤은 MI 무첨가군과 비교할 때 첨가군에서 유의하게 감소하였다. 계란 포화지방산 조성은 MI무첨가군과 비교할 때 첨가군에서 낮았으나 불포화지방산은 그 반대로 유의하게 높았다. 본 연구결과는 미세캡슐화 이눌린을 산란계 사료 내 첨가해주면 혈액지질 감소에 의해 계란품질을 향상시킬 수 있음을 시사해준다.

For investigate intracellular function and role of genes in the biological processes, various gene delivery methods into cell have been developed. Many studies performed to construct optimum conditions of gene delivery into cells and tissues. In this study, we examined efficiency of gene delivery-complexed with cationic lipid vector in human cancer cell lines. GFP plasmids were complexed with cationic lipid and transfected into human cancer cell lines at different concentrations. And then, expression of GFP was analysed with fluorescent microscope and FACS. To determine efficiency of gene delivery, we investigated GFP expression level in various cancer cell lines. GFP expression cells were not shown in hepatocellular carcinoma cell line HepG2 and lung carcimona cell line A549 after 24hr transfection, while, GFP expression cells were observed at 500ng concentration after 48hr transfection. In colorectal carcinoma cell line HCT116, GFP expression cells were observed at 100ng and 500ng concentrations after 24hr transfection and slightly increased at 48hr. After transfection into ovary adenocarcinoma cell line SKOV3, we could found that many cells expressed GFP at 500ng concentration after 24hr and highly elevated GFP expression cells after 48hr. For further evaluate gene expression level, we confirmed GFP expression level by using FACS analysis after 48hr transfection. As a result, HepG2 was expressed GFP in very low level at 10ng, 100ng, and 500ng concentrations. We also identified that GFP was expressed low level at 10ng and 100ng in HCT116 and A549, but highly increased at 500ng concentration to 14.19% and 16.57%, respectively. In case of SKOV3, GFP expression was highly elevated to 13.14% at 100ng and 58.10% at 500ng compared with 10ng transfection. By Comparing efficiency of gene expression among cancer cell lines, GFP expression was similar with cell lines at 10ng transfection, but significantly differed from cell lines at 500ng higher concentration. Additionally, GFP expression level of SKOV3 was showed about 10 fold higher than HepG2, and about 4 fold higher than HCT116 and A549 at 500ng. These results demonstrated that efficiency of gene delivery-complexed with cationic lipid vector was the highest in SKOV3, while HepG2 was showed the lowest efficiency. Taken together, we could determined that efficiency of gene delivery into cells differed from each human cancer cell lines. Our study suggest that cellular properties should be considered in gene delivery-complexed with cationic lipid vector to improve cellular expression efficiency of gene.

The objective of this study was to determine the feeding effect of a diet containing Cordyceps with fly pupa on the changes in blood lipid profile from broiler chickens, fatty acids and thiobarbituric acid reactive substances (TBARS) in chicken meat. A total of 360 chicks (Ross strain 308) were divided on hatch day into four treated groups with respect to a 35-day feeding regimen: T1 (control group), T2 (2.0% Cordyceps with fly pupa), T3 (3.5% Corceps with fly pupa) and T3 (5.0% Cordyceps with fly pupa). Blood triacylglyceride and total cholesterol level was significantly decreased by 5.32-10.63% and 9.23-12.62%, respectively, in groups T2, T3 and T4 when compared to T1 (p<0.05). Water holding capacity was significantly highest in T2 (p<0.05), while there were no significant differences among groups T2, T3 and T. In chicken meat, the ratio of saturated fatty acid to unsaturated fatty acid was high in the T3 and T4 groups, the ratio of n-6 to n-3 fatty acid was low in the T2, T3 and T4 groups and oleic acid (18:1n-9) was high in the T2, T3 and T4 groups, when compared to T1 (p<0.05). TBARS tended to increase according to the storage time (in days), and was significantly lower in the chicken thigh muscles with skin in groups T2, T3 and T4 as compared to T1 (p<0.05). These results suggest that a diet containing 2.0-3.5% of Cordyceps with fly pupa may decrease blood lipid and improve both the shelf-life and quality of broiler chicken meat.

The current study was carried out to investigate the effect of addition of Rhus veniciflua Stokes oil (RVSO) and black garlic extract (BGE) on the lipid oxidation in Hanwoo (Korean cattle) beef model systems. The RVSO at 0.2% inhibited the TBARS (2-thiobarbituric acid reactive substances) formation when tested in liposome model system. The antioxidant effect of RVSO was further found to be similar to 0.2% butylated hydroxy toluene (BHT) and 0.01% vitamin E. On the other hand, BGE at 0.1% also showed the inhibition of TBARS formation in 4% NaCl-added Hanwoo beef patty and found to have slightly lower (p<0.05) effect than 0.1% vitamin E but higher (p<0.05) effect than 0.1% BHT. Results of this study indicated that both RVSO and BGE possess strong antioxidant effects and help to increase the oxidative stability in Hanwoo beef products.

This study was undertaken to find out the effect of cholesterol and serum albumin on sperm ability and lipid peroxidation levels period to the liquid storage of miniature pig sperm. Ejaculated semen from miniature pigs was collected by gloved-hand method into a pre-warmed () thermos bottle, and extended with Modena solution {with and without BSA, methyl-beta-cyclodextrin (-cholesterol) and cholesterol loaded cyclodextrin (+cholesterol)}. Each semen was assessed for viability (SYBR-14/PI staining) and acrosome intactness, intensity and capacitation status by chlorotetracycline (CTC) staining at 1, 3, 5, 7 and 10 days of storage. At for the effects of cholesterol and serum albumin on lipid peroxidation, semen were incubated with (), and lipid peroxidation level were measured by flow cytometry using the lipid peroxidation reporter probe . The result, lipid peroxidation level in sperm added with cholesterol were lower in compared to the added sperm with serum albumin. Also, added cholesterol to sperm had significant (p<0.05) higher viability when storage for 7 and 10 days and lower when 10 days of storage percentage of acrosome-reacted sperm (AR pattern) in acrosome state as say result compared to other treated groups. In conclusion, role of cholesterol during lipid storage in miniature pig spermatozoa was protected boar spermatozoa from lipid peroxidation prior to lipid storage. Addition serum albumin during lipid storage in sperm may be induce sperm membrane damage by lipid peroxidation. Therefore, addition of cholesterol to miniature pig sperm will be lead to extension of liquid storage periods.

Comparative effect of oyster mushrooms on plasma, fecal lipid profiles, liver and kidney functions were evaluated in hyper and normocholesterolemic rats. The feeding of hypercholesterolemic rats with 5% powder of fruiting bodies of oyster mushrooms i.e., Pleurotus ostreatus, P. sajor-caju and P. florida reduced the plasma total cholesterol level by 37%, 21% and 16%, respectively and triglyceride level by 45%, 24% and 14%, respectively. LDL/HDL ratio decreased by 64%, 45% and 41% for P. sajor-caju, P. ostreatus and P. florida fed rats, respectively. Mushroom feeding also reduced body weight in hypercholesterolemic rats. However, it had no adverse effect on plasma bilirubin, creatinin and urea nitrogen level. Mushroom feeding also increased the total lipid and cholesterol excretion through the feces. The present study reveals that feeding of 5% oyster mushroom powder do not have detrimental effects on the liver and kidneys rather may provide health benefits for the cardiovascular-related complication by decreasing the atherogenic lipid profiles.
